改良后吸痰注射器的吸痰效果研究

Effects of improved suction syringe on suction

目的对一种在转运患者过程中所使用的改良后吸痰注射器的吸痰效果进行临床应用研究。方法选取2015年1—9月温州医科大学附属第一医院急诊抢救复苏室留观的经口气管插管机械通气患者50例，按照随机数字表法分为试验组（n=25）和对照组（n=25）。试验组采用改良后吸痰注射器进行吸痰，对照组采用壁挂式吸引器进行吸痰，对两组的吸痰效果和黏膜损伤率进行比较。结果两组患者在吸痰效果和黏膜损伤方面差异无统计学意义（P〉0．05）。结论研究发现改良后吸痰注射器能取得与壁挂式吸引器相同的吸痰效果，且不会增加黏膜损伤的发生率，可用于临床转运途中已建立人工气道的患者。

Objective To explore the effects of improved suction syringe used during transporting patients on suction. Methods A total of 50 patients with oral tracheal intuhation mechanical ventilation were selected in Emergency Room of the First Affiliated Hospital of Wenzhou Medical University from January to September 2015, patients were divided into experimental group and control group by the random number table, 25 cases in each group. Patients in experimental group were treated with suction with the improved suction syringe. Otherwise, patients in control group accepted suction with wall-mounting type aspirator. We compared the effects of suction and the rate of mucosa injury in two groups. Results There were no statistically significant differences in effects of suction and the rate of mucosa injury between the two groups （P 〉 0.05）. Conclusions The improved suction syringe can achieve the same effects of suction with wall-mounting type aspirator and will not increase the rate of mucosa injury. It can be used in patients with artificial airway during clinical transportation.
